STARTING DEVICE FOR EXPLOSIVE-ENGINES.

Application led .Tune 3, 1915.

To all 'whom it may concern:

Be it known that I, ORME F. LIPPINCOTT, a citizen of the United States, residing at Kenesaw, vin the co-unty of Adams and State of Nebraska, have invented certain new and` useful Improvements 1n Starting Devices for j Explosive-Engines; and I do hereby declare the following to be aV full, clear, and exact description of the invention, such as will enable others skilled in the art t0 which it appertains to make and use the same.

My invention relates to new and useful improvements in starting devices for explosive engines, and my object' is to provide in conjunction with a sparking plug a jacket for carrying the sparking plug and a chamber for carrying the explosive substances.

A further object is to provide a sleeve in connection with the cylinder of the engine into which the sparking plug and parts connected thereto is to be introduced. And a further object is to provide aquick detachable locking means for securing the sparking plug in the sleeve.

Other objects and advantages will be hereinafter set forth and more particularly pointed out in the accompanying specification.

In the accompanying drawings which are madea part of this application, Figure 1 is an elevation of a portion of a cylinder sho-wing my improved device attached thereto, and Fig. 2 is a vertical sectional view thereof, showing the spark plug in full lines.

Referring to the drawings in which-similar reference numerals designate correspo-nding parts throughout the several views, 1 indicates the cylinder of a combustion engine which may be constructed in the usual or. any preferred manner and having an opening 2 therein which is interiorly threaded to receive the threaded end of a sleeve 3. Adapted to be introduced into the outer end of the sleeve 3 is a cylindrical jacket 4, the outer end of which is provided with a collar 5, the inner edge of said collar forming a shoulder to abut against the end of the sleeve 3, the interior of the collar being threaded to receive a locking nut 6 which serves'to hold the spark plug 7 properly seated in the jacket.

In order to securely lock the jacket 4 within the end of the sleeve 3 and at the same time render the same quickly detachable therefrom, a lug 8 is provided on the outer face of the jacket 4, said lug coacting with a Specication of Letters Patent.

Patented Feb. 22, 191.6.

Serial No. 32,005.

from the outer end of the sleeve 3 so that when the lug is entered in the open end of the slot and moved inwardly its full distance and thenrotated to enter the same in the angular portion of the slot, the jacket and parts carried thereby will be securely held in engagement with the sleeve.

In order to obviate any possibility of the jacket rotating within the sleeve to register the lug with the open portion of the slot 9, the lug is provided with a recess l0 into which is introduced a locking latch 11, a spring 12 being entered in the recess above the latch to normally hold the same in lowered position. The projecting end o-f the latch is adapted to engage a notch 13 in the sleeve 3 and when so engaged prevents rotation of the jacket 4. In order to readily remove the latch from engagement with the notch, a pin 14 is attached to the latch 11 and extended through a slot 15 in the lug, the outer end of the pin being in position to be readily grasped to raise the latch.

The spark plug 7 may be of any preferred make and extends into the jacket to a point adjacent the inner end thereof, saidplug having a pin 16 which is adapted toc0- operate with with a pin 17 carried by the end of the jacket 4, said pins coperating to produce a spark when an electric current is introduced therethrough.

Surrounding the reduced end` of the jacket 4 is a. tube 18, which tube extends beyond the inner end of the jacket and to a point adjacent the inner end of the sleeve 3, said tube forming a chamber for the reception of any suitable form of explosive material 19, said explosive material also being packed around the sparking pins 16 and 17 so that when the spark is created at the gap between the two pins, the explosive material will be exploded.

This device is designed for the purpose of u is reintered into the sleeve and interlocked therewith through the medium of the lug and bayonet shape slot previously described. The piston is thenproperly set within the cylinder and a switch 20, or other suitable device, operated to close the circuit between the battery wires 2 1 and 22 which will result in directing a current through the sparking pins 16 and 17 and causing a spark in the gap between said pins, such sparks igniting the explosive material and causing the same to explode, the force of the explosion within the cylinder causing the piston thus Yoperated t`o start the engine. Instead of using the interlocking means shown between the sleeve and jacket, any other suitable means may be employed as may be desired.

This device can be very cheaply constructed and readily applied to use in connection with any form of internal combustion engine and as many charges of the explosive material as may be desired, may be entered into the tube and fired through the medium of the sparking arrangement.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent of the United States is l. A starting device for engines comprising the combination with a cylinder having an opening therein, and a sleeve extending from said opening, of a jacket, a. tube connected to the inner end of the acket adapted to contain an explosive powder, a sparking arrangement carried by the jacket comprising a pair of pins connected in circuit with the positive and negative poles of an electric generator, a locking nut adapted to secure the sparking arrangement to the jacket, a lug adapted to interlock with a slot formed in said sleeve and a spring actuated latch carried by the lug adapted to interlock with the sleeve and hold the jacket against rotation.

2. A starting device for engines comprising the combination with a cylinder having a hollow sleeve projecting therefrom, said sleeve having a slot at its outer end and a notch cooperating with the slot, of a jacket having an enlarged collar at its outer end, a sparking device carried by the jacket comprising a pair of pins connected in circuit with the positive and negative poles of an electric generator, means to lock the sparking device to the jacket, a tube at the inner end of the jacket adapted to contain an explosive powder, a lug on the jacket adapted to cooperate with the slot in the sleeve and interlock therewith, aV spring pressed latch slidably mounted in said lug adapted to engage the notch in the sleeve and hold the jacket against rotation and an operated pin carried by the latch.

A starting device for engines, comprising the combination with a cylinder and a hollow sleeve connected therewith, said sleeve having a bayonet slot in its outer extremity, of a. jacket, a tube carried by the jacket adapted to contain an explosive powder, a sparking arrangement carried by the jacket comprising a pair of pins connected in circuit with the positive and negative poles of an electric generator, a lug integral with the jacket and adapted to enter and interlock with said slot, a latch slidably mounted in the lug and adapted to interlock the parts of the sleeve and hold the jacket against rotation, means to normally hold the latch in extended position, and means whereby the latch may be operated to release the same from engagement with the sleeve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
